I have a WDTV Live connected to an Onkyo amp and 24Hz capable Panasonic TV over HDMI.
If I select Digital audio output from the WDTV and play an MKV file containing AVC and DD 5.1, sometimes the file will play fine, while on others the sound and video are out of sync pretty noticeably.
MediaInfo doesn’t seem to show any great differences between the files that seem to work (maybe they’re out too but not by so much) and the files that clearly a long way out (maybe 200 - 300ms as a guess).
I’ve seen posts from people complaining about this problem for a long time, but I’ve been unable to find any that have a solution. I’ve tried three different firmware versions, none of which made any difference. The only temporary fix is to use Stereo output, but that is not a solution.
Surely a problem as major as this must have been solved by now. Does anyone have any ideas?
